SPECIFICATION forming part of Letters Patent No 349,177, dated September14, 1886.

Application filed November 9, 1885. Serial No. 182.224. (No model.)

To aZZ whom it may concern:

Be it known that l, COLUMBUS K. Roenns, of Salem, in the county of Essexand State of Massachusetts, a citizen of the United States, haveinvented a new and useful Improvement in Elevators, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forminga part of this specification, inexplaining its nature.

This invention has for its object an improvement in the shipping deviceof elevators and in the arrangement of the winding-drum with relation tothe elevator-rope and the counterpoise, and also an improvementin theframe supporting the di'iviiigwheels, whereby the belts thereto may beled horizontally as well as vertically, which is the usual way ofleading belts at present.

In the drawings, Figure 1 is a side elevation, and Fig. 2 a plan view,of an elevator hoistinggear. Fig. 3 is a -plan detail of the shippingdevice, and Fig. 4 an elevation detail of the shifting-wheel and itsengagements with the shipping device. Fig. 5 is a vertical centralsection of the elevator-well and an elevation of the shipping device.

Like letters indicate like parts in all the figures.

A is the base or frame of the machine, which rests, as shown in Fig. 1,upon posts and webs, and has the web removed near the bottom, adjacentto the driving-pulleys O C C. This is done in order that the belts whichengage with thesepulleysC C may be led horizontally to the pulleys ofthe prime mover.

The rope-drum B is very much of the usual form,and is mounted on a shaftwhich is trans verse to the shaft on which the pulleys C C C aremounted. The drum-shaft is driven from the pulleyshaftby gearing in anyusual way.

The counter mi-se is attached to a rope which is led around thewinding-drum in an opposite direction from the elevator-rope, whichcounterpoise-rope is marked 2', while the elevator-rope is marked I. Itwill be observed that by this construction the counterpoise-rope has atendency always to rotate the windingdrum in such a direction as to liftthe elevator, and that the unwinding of the elevator-rope 1 tageouslythan in the other method ordinarily in use.

On the end of the drunrshaft is mounted the shipping-wheel D, aroundwhich the usual shipping-rope, J, is wrapped for the purpose ofrevolving it. This wheel is mounted by a screw on the drum-shaft, asshown in Fig. 2, and runs in or out, toward or from the winding-druln,as the drum is revolved upward or downward. Dogs K, fixed upon thewindingshaft, serve to come in contact with projections on the face ofthe wheel when it is run a sufficient distance in either direction forthe car of the elevator to reach the extremities of the shaft.- These(logs serve to move theshipping-wheel, and thus shift the driving-belton the .loose pulley C This arrangement of mounting the shipping wheelon a screwthread of the drum-shaft is not novel. From the inner face ofthe shipping-wheel D there projects toward the windingdrum a lug, N.(Shown in elevation in Fig. 4 andin plan in Fig. 2.) This lug is formedon the arc of a circle concentric with the center of the shippingpulleyD, and on either side of it, projecting from the same face of thepulley, are the pins a a. Upon the frame of the machine are arranged inguides two shipping-slides, E E, the slide E carrying the shipper F,which shifts the driving-belt for one direction betweenthedriving-pulley C and the loose pulley C The shipping-slide E actswith levers G G,which reach from side to side of the machine, and aregeared together with segment-gears at the center over the shaft ofpulleys O 0 G On the frame of the machine, opposite to the frame wherethe shipping-slides E E are found, is another shipping-slide, E carryingthe beltfork F, which serves to transfer the opposite driving-beltbetween the tight pulley G and the loose pulley 0 Two standards, 0 o,are arranged one upon the slide E and the other upon the slide I andengage with the pins a a and lug N.

By reference to Figft it will be seen that when the lug N is arranged sothat a tangent along its center will be nearly horizontal each ot' theshipping-levers will be in such a position that if the wheel 1) berotated so that its top moves to the right the lug X will move alongover the top of the standard 0, and the slide E, attached to saidstandard, will not be affected by the movement ol'the shippi ng-wheelI), while the pin a will at the same time move the standard, 0' and theslide 1 attached to it, and throw the lovers G G, the slide E andshaft-belt from the loose pulley to the driving-pulley C, and the lengthof the movement of the standard 0, and slide to which it is at taehed,being indicated by the dotted standard shown in Fig. t at o", and themovement of the lug N being shown in dotted lines to the right of thelug N, marked in full lines in the same figure. 11' it now be desired toreverse the movement of the elevator, the lug N will be engaged with thestandard 0 until it has been moved back into its first positioinwhen itwill begin to travel over the top of the standard o, and the pin a willcome in contact with the standard 0, moving the shippingslide E and fork1 attached to it, and so shippingits belt from the loose pulley U to thedrivingpullcy C.

I have arranged for use in connection with the rope .l the levers 1*,which are pivoted to the elevator-uptake, and arearranged at the 5 sideof the well so that the car may pass them, and so as to project throughholes in the well of the elevator to a position immediately above thevarious tloors, and they carry the blocks a, fastened to the rope .l,and which are secured to the lovers to permit the swinging movementthereof. Upon the movement of either of the lovers up or down the rope.T is moved either up or down. The object of this part of the inventionis to provide means for 1 operating the car from any door of thebuilding without reaching into the elevator-well, so that; a personstanding on any floor can by the movement of the lever operate theelevator and cause it to be moved to the floor that he is on, or to anyother lloor that he may wish.

For the purposes intended to be served by this invention sundry deviceshave been already described in Letters Patent, among others, to C. 1).Moore, No. 116,699, of January 20, 1874, to G. C. itewksbury, ReissueNo. 10,192, of August 29, 1882,.t0 Morse and Tyson,, No. 291,217, ofJanuary 1, 1884, and James 0. Fernald, N 283,586, of August 2.1., 1883,and I do not claim any of the devices shown and described in thesepatents, but desire to patent only the devices and combina tions whichdiil'er from them and are novel with me.

Having thus fully described my invention, what 1 claim, and desire tosecure by Letters Patent of the United States, is

l. The combination of the reciprocating shipping-slides E I) with eachother by the pair of geared levers (t G, substantially as described.

2. The combination of the shipping-slides lil E with the shipping-wheelD by means of the plain standards a c, erected on and fixed to theslides E l), and the plain lug N and pins a a, projecting from the faceof the shipping wheel, substantially as described. 7

3. In combination with the shipping-rope of an elevator, arranged withinthe elevatorshatt, but outside ot' the elevator-car, a single leverpivoted to the wall of said elevatorshalt, fastened to saidelevator-rope and having its power end projecting through the wall ofthe elevator-shalt to serve as the handle of a shipper-arm, whereby thedrivinghelt may be shifted and the motion of the elevator controlled atthe landings by a single lever-handle, substantially as described.
